GHALKLESS BILLIARD-CU'E TIP.

Application filed June 14, 1924. Serial No.. 719,984.

To all whom it may concern.-

Be it known that I, JOSEPH S. PIGA, a citizen of the United States,residing at Owendale, in the county of Huron and State of Michigan, haveinvented certain new and useful Improvements in Chalkless Billiard-CueTips; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to billiard cue tips, and has for one of itsobjects the provision of an article of this character which will notrequire the use of chalk in order to prevent its slipping on a billiardball when a player is making a shot, and to attain this end I provide atip having a roughened impact end.

A further object of the invention is the provision of a cork tip forbilliard cues having a roughened impact end.

A still further object of the invention is the provision of a novel andsimple process of providing a cork tip for billiard cues with aroughened impact end.

In the accompanying drawing forming a part of this application:

Figure 1 is a view in side elevation of a fragmentary portion of abilliard cue provided with a tip embodying my invention,

Figure 2 is a side elevation of a fragmentary portion of a billiard oneprovided with a slightly modified form of the tip,

Figure 3 is a View in side elevation of the blank from which the tip ismade, and

Figure A is a sectional view of the cork slab from which the blank ismade.

Referring to the drawing by reference numerals, 1 designates the forwardportio..1 of the billiard one and 2 my improved tip. The tip 2 is ofcylindrical formation and it may be provided with a plain impact end 3as shown in Figure 1 or with a convex impact end 4: as shown in Figure2. The tip 2 is made from cork having a minutely roughened textureprovided by subjecting the cork to the action of muriatic or any othersuitable acid.

In practice, I stamp up cylindrical blanks 5 from a slab 6 of cork.Blanks 5 are subject roughened, after which they are dried with- I havelearned out the use of artificial heat.

from actual experience that the desired roughening of the texture of theblanks may be produced by subjecting the blanks to a muriatic acid bathfor a period of twenty minutes. If the impact end of the tip is to be ofconvex formation, said end may be provided either before or aftersubjecting the blanks to the action of the acid.

The minutely roughened texture of the tips prevents them from slippingon a billiard ball when a player is making a shot, and owing thereto theuse of chalk is unnec essary. As the entire texture of the tip is rough,the impact end thereof may be trimmed from time to time without reducingits nonslipping characteristic, and as the roughness of the texture isof minute formation accurate shots may be made with a billiard cueequipped with the tip.

WVhat is claimed is 1.' A billiard cue tip made of cork having aroughened texture, produced bythe corrosive action of an acid.

2. The herein described process of making JOSEPH S. PIGA.
